The correct option is: B. 
<u><em>Explanation</em></u>
<u>The general form of growth equation</u> is:
, where A = final amount, P = initial amount, r = growth rate in decimal form and t = time duration
Here, the speed of the rocket at the beginning was 5,000 kilometers per hour and at the end will be 25,000 kilometers per hour. The speed increases at a rate of 4.3% per minute.
That means, 
Now <u>plugging these values into the above equation</u>, we will get......

So, the equation that could be used to determine the time for the speed of the rocket to reach 25,000 kilometers per hour will be: 
Answer:
57
Step-by-step explanation:
408-9 =399
399/7 =57
Since they are vertical angles, they equal each other. Therefor the equation would be: 30x-29 = 20x+21
10x = 50
X = 5
After, you plug whatever x is back into the other equations.
20(5)+21 = 121 and 30(5)-29 = 121
Answer:
10,000
Step-by-step explanation:
The link capacity is 10^9 bps; the link usage is 10^5 bps per user, so the number of users that can be supported is ...
(10^9 bps)/(10^5 bps/user) = 10^4 users
